CROSS EQUALIZATIUN 0F SPRING-RIGGING- meagre.

\ Application filed October 31, 1918.

To all whom it may concern:

Be it known that T, WILLIAM F. Kisser, Jr., a citizen of the UnitedStates, and residing at Altoona, Blair county, State of Pennsylvania,have invented certain new and useful Improvements in Cross Equalizationof Spring-Rigging, of which the following is a specification.

As is well known the spring rigging in a locomotive is arranged as athree-point suspension. For example, in a locomotive having two completeengines under one boiler, the spring rigging on each side of the rearengine is independent of that on the other, but equalized throughout itsfull length. Thus each side forms one point of support of thethree-point suspension. The front engine is equalized throughout and hasa cross equalizer in front of necting the two equalizers on the sides,there by providing'the locomotives of the consolidation type, theequalizing springs between'the first and second. pairs of drivers areomitted and one end of each equalizer overthe first and second drivingboxes is anchored to the frame, either directly or to a helicalspringresting on the frame. The cross complished by means of asemi-elliptic spring. However, in some instances such a spring can notbe used and obtain sufficient flexibility. I The present inventionrelates to a cross equalization construction which is designed to takethe place of the semi-elliptic spring arrangement used heretofore andgive more room for other parts of the locomotive. To this end atransverse equalizing bar has been substituted for the semi-ellipticspring artransverse bar carries on WlllCll is supported the rangement,and this helical springs rear end of the truck equalizer.

The features of novelty and objects of the invention will be apparentfrom the description taken in connection with the drawings,

' Fig. 4 is a top" plan view of the transverse equalizer; and

Fig. 5 is a side elevation, partly in section of said equalizer.

My invention is adapted for application in connection with locomotiveshaving different arrangements of spring rigging. As shown, there are theusual side equalizers A, A, adjacent to the front drivers and a centrallongitudinal truck equalizer B having its front bearing upon the frameof the pony truck.

Between the first driver wheels 1 suspend an improved equalizerconsisting of a cross bar provided with bearings for springs 2, 2, 2, ofany suitable character, helical springs being shown, and upon a cappiece 3 resting on said springs is a bearing for the rear end of thetruck. equalizer bar B. As shown the e ualizer bar D is suspended ateach end to a anger 4 suspended by side legs 5, 5, from the adjacentside equalizer A.

In the construction shown the equalizer bar D is cast in the form of aframe having a ends of the springs is provided with lugs 10' centeringWithin the springs and with a central bearing face w for the end of theequalizing lever b. p

By the use of the transverse equalizing bar with spring supports for thecentral longitudinal equalizer, I secure a much morecompact arrangementof parts than is possible in the ordinary construction wheresemi-elliptical springs are employed.

Without limiting myself to the arrangement and construction of partsshown, I claim as my invention:

1. The combination in a locomotive, of a transverse suspended equalizerbar provided with springs and a bearing on' said springs for the rearend of a central longitudinal I equalizer, substantially as set forth.
